Chronic arsenicosis is a major environmental health hazard throughout the world, including India. Animals and human beings are affected due to drinking of arsenic contaminated ground water, due to natural mineral deposits, arsenical pesticides or improperly disposed arsenical chemicals. Arsenic causes cancer with production of free radicals and reactive oxygen species (ROS) that are neutralized...

Context: Arsenic has metallic and non-metallic properties. It is widely found in sulfide ores belongs to the nitrogen family. used as an insecticide due its high toxicity. caused many environmental concerns, including widespread availability of arsenic environment, biological toxicity, exploitation. Potential routes exposure humans include drinking water, industrial manufacturing, diet, cosmeti...

Arsenic intoxication represents a worldwide health problem and occurs mainly through drinking water. Arsenic, metalloid naturally occurring element, is one of the most abundant elements in earth’s crust, whose toxicity depends on reduction state. The trivalent arsenicals are more toxic than pentavalent arsenicals. In state, inorganic organic arsenic may react with thiol groups proteins inhibiti...

In various Latin American countries such as Argentina, Chile, Mexico, El Salvador; Nicaragua, Peru and Bolivia, at least four million people drink water containing arsenic at levels which pose a risk to their health to such an extent that in certain areas this has become a public health problem. This is a compilation of work carried out on the problem of arsenic in drinking water and its effect...

Arsenic (As) is a widely distributed toxic element in the environment and microorganisms have developed resistance mechanisms in order to tolerate it. The cellular response of the chemoorganotrophic arsenite (As[III])-oxidizing α-Proteobacteria, Sinorhizobium sp. strain A2, to arsenic was examined in the present study. Several proteins associated with arsenite oxidase and As resistance were sho...

Exposure to inorganic arsenic induces skin cancer and abnormal pigmentation in susceptible humans. High-throughput gene transcription assays such as DNA microarrays allow for the identification of biological pathways affected by arsenic that lead to initiation and progression of skin cancer and abnormal pigmentation. The overall purpose of the reported research was to determine knowledge buildi...

In the workplace, the arsenic is used in the semiconductor production and the manufacturing of pigments, glass, pesticides and fungicides. Therefore, workers may be exposed to airborne arsenic during its use in manufacturing. The purpose of this study was to evaluate the potential toxicity of particulate matters (PMs) doped with arsenic (PMs-Arsenic) using a rodent model and to compare the geno...

BACKGROUND Millions of people worldwide are exposed to dangerous levels of arsenic (above the WHO water standard of 10 ppb) in drinking water and food. Lack of nutritious foods exacerbates the adverse health effects of arsenic poisoning. The micronutrient selenium is a known antagonist to arsenic, promoting the excretion of arsenic from the body. Studies are in progress examining the potential ...

Arsenic pollution in aquatic environments is a worldwide concern due to its toxicity and chronic effects on human health. This concern has generated increasing interest in the use of different treatment technologies to remove arsenic from contaminated water. Constructed wetlands are a cost-effective natural system successfully used for removing various pollutants, and they have shown capability...
